Teens (ティーンズ) The morning of his first day at a new school, Wakamatsu Jirou accidentally helps capture a dangerous criminal, and rumours spread like wildfire. Now a living legend, he's the first and only line of defense against the delinquents that make everyone's lives miserable. Only problem is, he doesn't know the first thing about fighting! 3. Aoba ni Kaze (青葉に風, Fresh Leaves in the Wind) Class 5 wants to win the upcoming girls' softball tournament, but with school idol Yamazaki Misa on class 2's lineup, not even their own male classmates want to cheer for them.
